Wouldn't it make more sense to do:

<script type="text/javascript" tal:content="here/myscript_js"></script>

and just have myscript_js print the Javascript without the enclosing script 
tags? 

   for i in range(1,4):
       print "var%d = %d" % (i, i)
 
   return printed

Or even better, if your script contents don't depend on values from the 
current request use:

<script type="text/javascript" src="myscript_js"></script>

which keeps the Javascript entirely outside the html so you don't have to 
worry about embedded angle brackets.
